    Abstract: Gynoecial morphology of Magnolia grandiflora is revised, with ‘follicles’ reinterpreted as condensed branching systems forming a flower-like syncupulate infructescence (‘secondary flower). Flowers appear on the main axis in the axils or on basal ramifications of gynoecial paracladia, those developing into fruits being incased by glandular calyptras... Show More

    Abstract: Anti- oxidants are crucial to human health. They have capacity to neutralize the free radicals responsible for giving birth to a variety of diseases. A diet rich in foods with high levels of anti-oxidants is associated with longevity and good health. We tried to replace the chemical anti-oxidants by herbal anti-oxidants. In plants, the anti-oxidant... Show More

    Abstract: Anoxia and hypoxia, caused by excessive rainfall and inadequate drainage are the most common environmental stresses in upland crops after wetland rice in many regions of Asia. Such stresses and/or puddling of soil in rice culture often reduce the growth and yield of post-rice upland crops. This study examined the growth and yield responses of three... Show More

    Abstract: The tannosome, an organelle producing condensed tannins in the chlorophyllous organs of the Tracheohyta, is formed from the unstacked granal thylakoids by pearling into tiny spheres [1]. Other variants of intraplastidial ontogenesis of the tannosomes were investigated in the Tracheophyta by transmission electron microscopy. The “pearl necklace” mod... Show More
